How to close out a game by yourself?

So i just had a very frustrating game as illaoi top. I won lane hard got my turrets, took rift, got mid turrets. I was 5/0 at that point and calling my team for baron but no one would listen to me. I kept pushing and looking for team fights but my team was playing super passive for some reason. The whole time im still calling baron and its starting to tilt me so i push out a wave and get 5 manned. Still everyone is just farming even though we&#039;re ahead by a lot and i have no idea what to do. We start losing then the team finally decides to do baron, our riven jungle misses smite and we lose the game.
I don&#039;t know what I could have done to win it seems impossible to close out a game when your team doesn&#039;t communicate or listen.
